What is a Zener Diode?

A Zener Diode is a kind of diode that is designed to operate specifically in the reverse breakdown region. Its main application is to regulate and limit the DC voltage level. It features a higher reverse breakdown voltage than an ordinary diode; its structure consists of several layers. It is designed to start conducting current in the forward direction when the voltage applied to it reaches the Zener voltage.

How Does a Zener Diode Work?

A Zener diode\'s conduction works by a process called Zener breakdown. As the voltage applied to the diode reaches the breakdown voltage, it makes a hole in the reverse-biased depletion region, causing current conduction. This is known as avalanche breakdown that occurs when the electron-hole pairs that are generated by the applied voltage are accelerated by the electric field, causing further electron-hole pairs to be created by electron impact ionization.
